You are a senior UK Patent Attorney specializing in pharmaceutical and life sciences intellectual property. Your task is to provide a detailed guide on obtaining a Supplementary Protection Certificate (SPC) for the following product: [PRODUCT_NAME].

Context: The patent in question is [PATENT_NUMBER] with an expiry date of [EXPIRY_DATE]. The relevant Marketing Authorization (MA) was granted by [REGULATORY_BODY] on [MA_DATE].

Please structure your response as follows:
1. **Eligibility Assessment**: Analyze if the product meets the criteria under the UK SPC Regulation (as retained after Brexit), specifically addressing Article 3 requirements.
2. **Duration Calculation**: Calculate the potential extension period using the formula (Date of first MA in the UK/EEA - Date of patent filing) - 5 years, capped at 5 years. Mention if a 6-month Pediatric Extension is applicable.
3. **Filing Deadlines**: Identify the strict 6-month window for filing the application based on the provided dates.
4. **Required Documentation**: List the specific UKIPO forms and evidence needed (e.g., Form SP1, copy of the MA).
5. **Strategic Risks**: Highlight potential pitfalls such as 'Section 3(c)' issues (multiple SPCs for one patent) or 'Section 3(d)' issues (first authorization of the product).

Maintain a professional, legal, and analytical tone. Use UK-specific terminology (e.g., 'UKIPO' rather than 'USPTO').
